Specification of Letters Patent.

' Application filed January 14,- 1909. Serial No. 472,194.

proved Valve, of which the following is a tull, clear, and exact description. I I

My invention relatesto valves of the kind used in connection with flushing tanks.

A more particular purpose of my improvement 1S to produce a valve having a cup-movable in relation to an inlet pipe, this cup being provided with a hood for preventing excessive splashing of the water when the cup raised for the purpose of allowing water, under considerable pressure, to refill the tank. In this connection it may be stated that flushing tanks are frequently refilledby water at excessively high pressure, ranging from 50 to 150 pounds per square inch. It is not always desirable to diminish this pressure, for the reason that it must be main.- tained for considerations independently of the operation of the tank. ,Vhen, however, water is forced into the tank under such exundue splashing of water in the tank, and in many instances a spray of the liquidis thrown over the top of the tank, to the annoyanceof people in the immediate vicinity. I find that the trouble ust mentioned is due mainly to the fact that in the type of valve ordinarily used there is a cup which covers and uncovers a nozzle, and that, in order to avoid the trouble, it is necessary to prevent water from escaping upwardly around the cup'as the latter is raised. f

Reference is to be had to the accompanying drawings forming a part of this specifitherewith; and Fig; 2 is afragmentap tical section, on an enlarged scale, showing the details of the inlet valve.- A

A tank: is shown at 3 and is provided internally with a lining a which may be of metal. At 5 is an inlet pipe and at 6 is a union. A tubular'sleeve 7 is connected to the pipe 5 by aid of this'union and is threaded externally. This tubular sleeve 7 Patented Dec. 7", 1909.

terminates at its upper end in a plate 8.

tevolubly mounted upon the tubular sleeve is a threaded nut 9 which eng: es a gasket 10 in such manner as to force the same against the under side of the tank. A post 11 integral with the plate 8 extends up \vardly from the latter. A pipe 12 extends through the post. 11 and upwardly therefrom into the top of the overflow pipe 13.

This pipe is connected with a plate 1.4 having a threaded tubular portion 15extending therebelow through the bottom of the tank. A threaded nut 16 is mounted upon the tuwhich is thus forced'against the under side of the tank. A cap 18 having'a general annular form is threaded internally and fittedupon the lowerend of the threaded tubular member 15. This cap 18 forms a union. between the tubular member 15 andthe outlet pipe 19.

At- 20is shown a ball valve which is provided with an annular gasket 21, and this gasket rests upon an annular seat 21 and so controls the flow of water from the tank.

At 22 is a float and connected with the same is an arm 23, this arm being provided. with an enlarged-portion 24, the latter be ing pivoted on the post 11.and connected by a pivot 26 with a cup 25, provided with a hole 27. A hood 32, integral with the cup 25, has a considerably greater diameter than the cup, and serves as a shield for preventing the splashing of water, as'hereinafter described. form of a segment of a sphere.

Mounted upon the plate 8 and partially sunken thereinto is a rubber gasket 28., A sleeve 29 threaded at its bottom, extends through the gasket 28 and is, in communication with the outlet pipe 5 through the medium of the threaded sleeve'7. The sleeve 29 is provided with openings 30,. one of which is in alinement with the lower end of the pipe 12. A gasket 31039 rubber mounted upon the upper end of the sleeve 29 and is held by aid of a screw 83. The opening 80 being substantially in alinement with the pipe 12 enables the water, when discharged. from the openings 30 into the tank, to find its way, to some extent, upwardly through bular extension 15 and engages a gasket 17 Thishood has substantially the the pipe 1 2, thereby causing a small discharge of water to take .place below the ball valve 20 wheneverthe tank is refilled. The

Water in the tank is shown at 34.

- The operation of my device is as follows: Whenever the ball. valve 20 is raised in the usual manner, the water flows freely-from the tank out through the pipe 19. The lowering of the water allows the float 22 todescend and this raises the cup 25 so as to uncover the holes 30. ,The' water now passing through the inlet pipe 5 isdischarged I throughthe holes 30 and a portion of this the tank. The hood 32 prevents this and confines the outflow of the .water within a two subscribing Witnesses.
